PATENT LEDGER-BOARD- SUPPORT FOR SCAFFOLDS.

SPECIFICATION forming part of Letters Patent No. 593,639, dated November 16, 1897. Application filed April 24:, 1897. Serial No. 683.681. (No model.)

To all whom it may concern: 1 Be it knownthat I, WILLIAM S. BRADLEY, a citizen of the United States, residing at New Britain, in the county of Hartford and State vView of the supporting-bracket.

A designates a portion of one of the uprights or posts of a staging, and Ba portion of one of the ledger-boards.

O is a bracket having a back surface designed to rest against one side of the post and at its upper end a seat or support 4 for the lower edge of the ledger-board to rest upon. The back surface-of the bracket C may be roughened or provided with any desired number of points, as at 5, Figs. 2 and 3, to take a better hold on the side of the'post A.- I pro vide said bracket with a chain 6, securely fastened thereto by one end in any proper manner-as, for example, by the bolt 7, which socures one end of said chain to one side of said bracket, leaving the other end of the chain.

free for use, as hereinafter described. At the opposite side of the bracket is a hooked lever 8, fulcrumed thereon in any proper manneras, for example, by means of the same bolt 7 that secures the chain to the bracket. After placing the bracket in position against the post, as shown, the free end of the chain is carried around the said post and one link thereof hooked upon the hooked end 9 of the lever 8 and said leverturned into a position to tighten the chain firmly on the posts. 'A pin 19 is then inserted in one of a series of holes 10, Fig. 2, to hold the lever 8 in place, as shown. The ledger-board B is then put in place on the bracket and secured by means of the holder 11, the lower end of which enters the holes 12 in the bracket, while its upper end is secured by a chain 13 and lever-cam 14. The said chain is secured by one end to the bolt 15 at the upper end of the holder 11 and passed around the post, with the lever-cam on the chain having its handle elevated. The chain is then secured to the other end of said bolt 15 by slipping one of the chain-linkson said bolt, after which the lever-cam 14: is turned down into the position shown to tighten the chain and press the ledger-board firmly against the post A. If desired, the back face of the holder 11 may be roughened or provided with points, as at 16, Fig. 2.

I have shown the support in Figs. 1 and 2 as applied to the middle portion of one of the ledger-boards. It is applied tothe meeting ends of two ledger-boards in the same way, with the single exception that the lower end of the holder 11 will, be inserted in the holes 17 of the bracket C instead of the holes 12 to accommodate the extra thickness of boards.

By my improvements I produce a simple and inexpensive support which may be quickly and conveniently applied and firmly hold the parts in place, while at the same time the posts and boards are not injured by nailing and may be used repeatedly.

I claim as my invention- 1. A ledger-board support consisting of the bracket, the chain secured by one end to said bracket and adapted to encircle a post, and the hooked lever mounted on the said bracket and adapted to receive the opposite end of said chain for securing and binding the chain in place substantially as described.

. 2. The combination of a supporting-bracket adapted to be secured to a post,with the holder 11 having its lower end fitted to engage said bracket, and the chain and lever-cam for securing the upper end of said holder substantially as described.

WILLIAM S. BRADLEY.
